Looking for advice
My current touring bike which is a modified 26 inch wheel mountain bike has 27 gears (3 front rings / 9 on sprocket). I am looking at installing a belt drive 11 speed internal hub (Alfine)
Has anyone any experience of doing this conversion and if so what problems did you encounter.
Was going to splash out and have electronic shifting too (Di2)
For belt drives, a special frame is required, as the belt can't be split, like a chain can for installation. They have a removable piece of frame to leave a gap the belt can go through.
Unlikely you'll be able to install belt drive unless your frame has already been designed to accept it.
I've run quite a few Alfine & Sturmey Archer hubs. The only issue you will have is people telling you that normal gears are better.
In reply to Mike, I've always run a front tensioner, far neater, generally out of the way and make getting wheels in and out a doddle.

Fairynuff... personally, I found another component spoiled the tidier bike I was after, but each to their own.
Won't all belt drive compatible frames have long dropouts though, for adjustment?
Think I'll stick with a chain for starters
> Interesting.... and pricey!
In that case, are you happy to go from 27 to 11 gears?
There's likely some duplication so you don't really have 27 but you'll probably notice quite a difference.
What frame is it? I've done a few IGH conversions at work.
I have an Alfine 8 (chain driven) on my Kaffenback commuter cross. Just passed 10,000 miles and it's had 2 oil baths and on its 2nd chainring/sprocket/chain. Typically 15-30 daily miles of towpath clag, trail mud and road salt. Faultless and cheap to run.
Yes it's a bit heavy, a little lossy and I yearn for the range of the 11 speed but I have little doubt that it won't do another 10k+ miles.
